Olea europaea tree named 'HIDshurtleff'

Abstract

A variety of olive tree, named ‘HIDshurtleff’. The ‘HIDshurtleff’ is an ornamental olive tree having a bright green leaf with a smooth texture and increased width and length, a very long weeping characteristic, extremely low leaf/material drop, and very hardy wind, animal and drought characteristics.

Description

CLASSIFICATION

The present invention relates to a new Olea Europaea tree.

VARIETY DENOMINATION

The new plant has the varietal denomination ‘HIDshurtleff’.

ORIGIN OF INVENTION

This invention relates to a new and distinct variety of Olea europaea named ‘HIDshurtleff’, which was discovered at the Hidden Springs Ranch in Santa Margarita, Calif. The plant to date is known only to exist within the boundaries of the Hidden Springs Ranch, and has not been offered for sale or described in any publication.

SUMMARY OF THE INVENTION

Among the features which distinguish the new variety from other presently available and commercial olive cultivars known to the inventor is the following combination of characteristics: a bright green leaf having a smooth texture and increased width and length, a very long weeping characteristic, extremely low leaf/material drop, and very hardy wind, animal and drought characteristics.

Asexual reproduction of the new variety by cutting as performed at Monrovia Nursery Company orchards in Visalia and Woodlake, Calif., and shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding asexual propagations. ‘HIDshurtleff’ may be asexually propagated by cutting. The cutting and grafting successfully occurred on the plant/rootstock Olea cv. ‘MONher’ in the United States. Sexual reproduction, such as speed propagation has not been attempted as no seed has formed from this plant.

COMPARISON WITH PARENT/CLOSEST COMMERCIALLY AVAILABLE CULTIVAR

Because the new olive is a naturally occurring mutation, there are no known parents with which to compare the ‘HIDshurtleff’. The closest commercially available cultivar to the new variety is the ‘MONher’ olive (U.S. Plant Pat. No. 5,649). Both olives produce either no fruit or few immature fruits each year. The new olive may be distinguished from the ‘MONher’ variety by the following combination of characteristics: the ‘HIDshurtleff’ has a weeping and cascading characteristic and the ‘MONher’ does not. The ‘HIDshurtleff’ has fewer lateral branches than does the ‘MONher’. In addition, the leaves of the ‘HIDshurtleff’ are greener and glossy, have a smoother soft texture, and are wider and longer, compared to the foliage of ‘Monher’.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying photographs illustrate the new variety and show the leaves and branches thereof depicted in color as nearly correct as it is possible to make in a color illustration of the character. Throughout this specification, color references and/or values are based upon the Colour Chart of The Royal Horticultural Society (2001) except where common terms of color definition are employed.
